When to spray lawn for crane flies?
I'm in the great lakes area - my climate is similar to Detroit, Buffalo,
Cleveland. Haven't had a frost yet. Is now a good time, or a bad (ineffective) time to spray my lawn to kill crane flies? |

But I've taken action recently and I've applies a bag of grub killer followed up with a hose-end spray of several jugs of liquid grub killer. Active ingredient is Sevin (Carbaryl). I believe that in my area, that early to mid october is the best time to apply Carbaryl to treat crane flies (aka leather jackets or leatherjackets) as they feed in their late instar growth stage. I will probably treat the area again in the spring to kill the damn things. The crane fly is NOT native to US/Canada, and by not eradicating it we are allowing a non-native species with no natural predator to become endemic in our ecosystem. That is NOT a beneficial outcome for our environment. Same is true for the emerald ash borer. Thousands, if not millions of ash trees (many of them healthy and un-touched) have been cut down to stop the spread of the ash borer. |
